My wife supports my interest in the hobby. I can pretty much do what I like within reason. I am extremely lucky.
My wife does like to ride trains to the Grand Canyon, the Durango & Silverton, Cumbres & Toltec, etc. I think that she likes the activities at the destination of these trains.
She will attend one or two train events per year especially if some of the other wives are involved. Beyond that, I am doing train stuff with all my buddies.
